Howard Stern would be happy to replace Simon Cowell on the American Idol judging panel — if program bosses promise to pay him enough — but Idol panelist Kara DioGuardi isn’t the only series judge that feels casting the notorious shock jock would be grave mistake.

The Chicago Sun-Times claims freshman A.I. expert Ellen DeGeneres has threatened to leave the series if Stern joins the team.

The paper writes: “According to a veteran ‘Idol’ staffer, ‘Ellen has told just about anyone who will listen that she’s totally opposed to the [Stern] idea,” making it clear if he is hired, she’d leave the show……’”

But Ellen may not have to worry about packing up her dressing room just yet, because a Fox executive says the chances of Howard being hired are next to nil.

“The Stern thing makes for good chatter, but is such a remote possibility, I can’t see it ever happening — at least in this life,” the exec said.

Last month, music mogul Simon revealed he is leaving the TV talent show to launch an American version of The X Factor. Since then, there has been much speculation about who will fill his spot on Idol.
